我们要解下面的方程:
[tex]\[ x - \frac{5}{6}x = \frac{3}{7} \][/tex]
首先,我们对方程的左边进行简化。将 [tex]\( x \)[/tex] 和 [tex]\( \frac{5}{6}x \)[/tex] 合并成一项:
[tex]\[ x - \frac{5}{6}x = \frac{1}{6}x \][/tex]
所以,原方程变为:
[tex]\[ \frac{1}{6}x = \frac{3}{7} \][/tex]
接下来,我们通过两边同时乘以 6 来消去分母:
[tex]\[ x = \frac{3}{7} \times 6 \][/tex]
[tex]\[ x = \frac{18}{7} \][/tex]
简化后,我们得到:
[tex]\[ x \approx 2.57142857142857 \][/tex]
因此,方程 [tex]\( x - \frac{5}{6}x = \frac{3}{7} \)[/tex] 的解是:
[tex]\[ x = \frac{18}{7} \approx 2.57142857142857 \][/tex]
[tex]\[ x - \frac{5}{6}x = \frac{3}{7} \][/tex]
